28Unless the register is in such a form as to constitute in itself an index, the company shall keep an index of the names inscribed in it, which shall—
(a)in respect of each name, contain a sufficient indication to enable the information entered against it to be readily found; and
(b)be kept at the same place as the register;
and the company shall, within 14 days after the date on which a name is entered in the register, make any necessary alteration in the index.
